(No lndelf) l/ l Y UNITED i y STAT-Es To all whom it may concern:

Be itknown that I, JOHN F. LEWIS, a citizen of the United States,residing at Scranton, in the county of Lackawanna and State ofPennsylvania, have invented certain new and useful Improvements inLubricators; and I declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to thetigures of reference markedthereon, which form a part of this specification.

This invention relates to that class of 1ubricators which are used toconvey lubricant to the inside of the steam chests and cylinders oflocomotive and other engines, and has for its objects to produce amultiple form of such lubricators to carry the lubricant to a pluralityof points to be lubricated, vgreater efciency and certainty of action-than, in those heretofore in use, and other objects as set forth inthis specification and embodied in the claims. v

To these ends the invention consists of the novel construction,arrangement, and combination of parts herein specied, and illustrated inthe accompanying drawings.

Referring to the drawings, Figure 1 is a top view of a lubricatorembodying my invention having certain parts removed. Fig. 2 is across-section taken on the -line .fr of Fig. 1 with the parts replaced.Fig. 3 is a minitied general view of the device, showing a mode ofattachment to the curved surface of a boiler. Fig. 4 is a view taken incross-section on the line y y of Fig. 2 looking toward theoil-reservoir. Fig. 5 is a view taken in cross-section on the line a zof Fig. 2. Fig. 6 is aview taken in cross-section on the line t t ofFig. 1. Fig. 7 is an enlarged detail View of the special valve used inthe device.

LUBRICATO R.

SPECIFICATION forming part of Letters Patent No. 653,420, dated July410, 1900. Application filed September 15 1898. Renewed February 17,1900. Serial No. 5,649. (No model.)

a bore 5 longitudinally bored into the end thereof to accommodate theend of the tube 5, which extends partially into the chamber 1, and thechamber lis enlarged at 25 to accommodate the end of the said valve. Apassage 28 also extends from the chamber 1 and surrounds the tube 5,connecting with the passage or chamber 8, from which any number In theillustration shown there are two duct-s leading from the said chamber 8through the sight-feed devices 8' and 8", which are designed to feedlubricant to the two separate steam-chests ofa two-cylinderlocomotive-engine, for which the device illustrated is particularlyadapted. Fitted into the bracket or member 6 and inclosing the up-dropnozzles 8 and 8" are glass sight-tubes 9 and 9', from which lead theducts or passages 20 and 21, emptying, respectively, into the passagesor ducts 14 and 15, which lead from the tops of the tubes 16 and 17 inthe condenser 3. They lead from 6 through the connections or nozzles 30and 31, respectively, whichare adapted to have coupled to them smallerpipes leading, respectively, to the right and left cylinders of thelocomotive. The parts 30 and 3l have attached to them the old-fashionedgreasecups 32 and 33, adapted tobe used in emergencies. They are adaptedto be closed by the valves 36 and 37 and provide for the ordinary methodof lubricating should the other parts of the device become broken 4ordamaged. The passages 8 and 8" are controlled, respectively, by theturn-valves 10 and 11, and the passages 14 and 15 are controlled aftertheir junction With the passages 2O and 21, respectively, bytheturn-valves 12 and 13, re-

spectively. The valves 12 and 13 have cylindrical projections 22 and 23ttin g loosely into the round passages 14 and 15, so that when the valveis turned a round or two the contents of the passage may be forcedthrough the small annular openings thus provided for it. The receiver 30is adapted to be screwed onto a short threaded shank on the top of themember 6, and the valve 7 is screw-threaded into a lug 27,' projectingdownward on the inside The stem of the valve 7 must be inserted thereinbefore the handle 7 is fastened thereon. -The member 6 is at? tached tothe reservoir 1 by means of the IOO through which the live steam pipeconnecting with the steam-boiler is attached at 3', and thelubricant-pipes, y

reaching to the steam-chests of the cylinders, are suitably attached tothe members 30 and 31 of the device. The turn-valve 7 is now opened andall of the other valves except 3G and 37, which are never opened duringthe operation of the main part of the device. Condensation-watercollecting'lin the chamber 3 is conducted downward through the passage4, passing through the tube 5 into the recess 5 and passing lthrough theopen annular space between the inner walls of the recess 5' and theouter surface of the end of the tube 5, whereupon it drops downward andcollects on the bottom of the reservoir 1, at the same time displacingand forcing the lubricant through the annular space 28 and into thechamber S, where it spreads and passes upward through the nipples 8' and8". The condensation-water from the tubes 16 and 17 will also graduallyfill the sight-tubes 9 and 9', which are made of glass, with water, andthe lubricant is floated thereby out through the passages 2O and 21,respectively, by means of which it is emptied into the outleadingpassages 14 and 15,1'espectively. The crooks 1S and 19 in the passages14 and 15 respeetively serve as traps by collecting water in their lowerangles, so as to prevent lubricant from passing upward through thepassages 14 and 15 should they become filled with condensation-water.Since the oil in that case might pass upward through one of them, itbeing buoyed by the water, and then float on the level of thecondensation-water, which in such case being as high as the upper endsof the tubes 1G and 17, the oil would be carried down the other tube,which being empty would convey it to one of the cylinders of the engine,so that the attendant would not be aware that both sides were not beinglubricated. lt is to prevent this occurrence for which these particularfeatures of my invention are designed. The ends of the tubes 16 and 17are intended to extend above the level of the condensation-water whichmay be contained in the chamber 3 and are each intended to conduct a jetof live steam out through the passages 14 and 15. The valves 22 and 23,respectively controlling passages 14 and 15, are not fully turned openduring the operation of the device; but the cylindrical portions 22 and23 form annular narrow passages steam forces the lubricant and spraysit. Of course the jet is allowed to be strong enough to continue todrive the lubricant through thepassages to the steam-chests of cylindersto be lubricated.

The parts 30 and 31, which are attached to threaded shanks on the member(i, so as to continue the passages 14 and 15, respectively, are adaptedto be used by filling the cups 32 and 33 with lubricant, then unscrewthe valves 3G and 37, when by closing the throttle of the engine whileunder headway the lubricantis drawn downward through the passages 34 and35 by the partial vacuum formed in the cylinders. This is never doneunless from s ome cause the regular mechanism is out of order.

An advantage in the construction of the valves 12 and 13 is that apartial turn or a number of turns of the said valves will not change theeffect or the size of the opening through which the lubricant issprayed, and therefore may be turned in the dark by the attendant tostop or start the lubricant, while the valves 10 and 11 are notinterfered with except at such times when the drop or lubricant may beseen passing up through the respective tubes E) and 9. It is during thetime that the valves 12 and 13, or one of them, may be turned off thatthe tubes 16 and 17 collect full of condensation-water, but with thetraps 1S and 19, which I havearranged in the passages, the lubricant isprevented from passing up through said tubes, and when either of thevalves are open in the usual way the pressure of the steam immediatelydrives the condensation water collected therein out through the annularopenings and then delivers lubricant as before. By the arrangeF ment ofclosing the passages 4 and 28 by the one valve 7 and by the extending ofthe end of the tube 5 into the recess 5 of the said valve I prevent adifficulty common with lubricators-viz., a mixing or emulsifying of theoil and water as the hot condensationwater is entering into thereservoir 1. By my plan the water will drop down from the end of thetube 5, while the oil will pass outward through the passage 28 from theedge of the reservoir. An advantage is also gained by having but the onevalve 7 to turn in closing off both these passages, and when the saidvalve is closed off the passage 1' may be opened and condensation-waterdrained olf and the plug 2 removed for replenishment of the reservoir.

Having thus described my invention, what I claim is- 1. In a lubricatorof the kind described, an oil-reservoir and a condenser, the saidcondenser situated at a higher level than said reservoir and having apassage for condensation-waterleading thereto through a tube projectinginto the upper part of said reservoir in substantially a horizontalposition, the said horizontal tube leading through an annularpassage-way provided for the exit of lubricant and adapted to contain aconsiderable portion thereof, in combination with a valve having acup-shaped end adapted to cover the end of IOO IIC

the tube aforesaid projecting into the oilreservoir, and to form withthe said annular passage around it, a temporary substitute for theoil-reservoir during the process of refilling, substantially asspeciiied.

2. In a lubricator of the kind described having an oil-reservoir andcondenser adapted to drive oil thereout by condensation-water, lthecombination of an induction-tube leading from said condenser in asubstantially-horizontal position and projecting inward of saidreservoir and adapted to lead condensationwater therein, with an annulareduction-passage for lubricant surrounding said inductiontube, anddelivery-passages extending from said annular passage with a cup-shapedvalve JOHN F.
